Description of drawings
Fig. 1 is the circuit theory diagrams that this utility model is used to start the automatic detection starting drive of fume cleaning system.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
In this utility model, upper equipment can be high frequency electric knife, laser surgery equipment, microwave operation apparatus etc.The signal input part of this utility model device is to be connected with upper equipment, and the signal output part of this utility model device then is to be connected with fume cleaning processing system (the next equipment) by the JP1 interface.In order to describe the annexation of this utility model device and upper equipment in detail, present patent application only is that example describes with the high frequency electric knife, and such explanation can not be as the scope of application of restriction this utility model device.Be connected with a section lead between the writing of indictments, appeals, etc. of high frequency electric knife and the main frame of high frequency electric knife, current transformer just is connected on the described lead.Whether the writing of indictments, appeals, etc. that current transformer is used to measure high frequency electric knife has electric current output in working order down.
This utility model is surveyed starting drive automatically and is included current transformer, rectifier circuit, operational amplification circuit, comparison circuit, delay circuit, drive circuit; Current transformer and produces voltage with this electric current by resistance R 1 when detecting upper equipment electric current is arranged, D1 is rectified into direct current signal by rectifier bridge; This direct current signal affacts on the next equipment after by operational amplification circuit, comparison circuit, delay circuit, drive circuit, thus after being implemented in upper equipment and quitting work 15 seconds described automatic detection starting drive just the next equipment of start signal output quit work.
